Meanwhile in the Feywild...

Willow Nightdew is the daughter of High Priestess Aralynn Nightdew and the Archdruid Fennel Nightdew. Her family has served the mysterious Night King and his court for centuries.
 
Early in her childhood, Willow was introduced to Sura, the daughter of the Night King and Queen. Sura and Willow became fast friends. Building pillow forts, sneaking treats from the kitchens, having wooden stick fights through the halls.
 
Soon after becoming friends with Sura, her brother, Melrom was born. The Queen, her mother’s friend, passed in childbirth. Sura blamed her brother, and Aralynn assured the children that sometimes there are things that can’t be healed and it was not Melrom’s fault. Willow was kind to Melrom after that. He didn’t mean to hurt his mother. Sura didn’t seem so convinced.
 
Willow never thought of the Night King as a mystery when she was a child. He was just the Night King, her mother’s friend and her best friend Sura’s dad. His name was just the Night King, he didn’t need another one. She never asked. She still has never asked or cared.
 
As she got older and interacted more with the different druids in her father’s circle, she realized how mysterious the Archfey and his family seemed to everyone else not in his inner circle. The druids who were not native to their court seemed the most perplexed. Fennel would explain away in a very free spirited way, and Willow adopted the same attitude.
 
She learned from her father’s circle about star maps, how to turn her shape into that of constellations, and formed a connection with a fey spirit in the form of a raccoon. Louis was his name. He would help her sneak snacks from the kitchens to take to Sura when they would have girls nights and braid their hair and gossip about the stuffy fey nobles and crushes.
 
One such crush for Willow was Melrom. Sura was never keen on her best friend being romantically entangled with her brother, and it kept them at a more on again off again state. Mostly Willow feeling guilty about Sura. That didn’t stop them from sharing a lot of firsts.
 
Fourteen years ago - The Solstice Festival. It was during an off period with Melrom when Sura had signed Willow up for a giant snail racing contest. Willow was more of the giant snail racing cheerleader than jockey, but she agreed. At the end of a neck and neck race with a satyr, it was determined that they tied. The gamesmaster declared them both winners and they both got to share the prize, an oversized bottle of wine. Cecelia Thornfiddle was taller than Willow by a few inches, had golden blonde hair, eyes the color of sea glass, and a smile that twinkled brighter than the starry form Willow was just starting to master.
 
She was smitten. Melrom was the past, Cecelia was her future. Melrom was hurt when Willow told him they would no longer be a thing. She promised him that she’d always be his friend and would support him regardless. He seemed to accept this, eventually.
 
She met Cecelia’s pet fox, Sebastian. He and Louis were fast friends. She spent more time in the woods with her, away from the palace. Sura would join them occasionally, when she didn’t mind third wheeling. They would bake together and garden in a little greenhouse attached to the side of Cecelia’s house. They’d spend time together with friends, playing music, telling stories.
 
Willow found herself one morning asking her to marry her. “Took you long enough.”
 
They were married soon after. The Night King officiated as they promised their lifelong love in front of their friends and family. Louis and Sebastian were their best men.
 
Ten happy years passed. Life is never perfect, but it felt close enough for the two of them. They spoke of children, and the possibility. Maybe they’d have children through magic, maybe adoption. They hadn’t quite decided, but they wanted them.
 
It was during another conversation about their future kids names while on a scouting round with Cecelia and a few of their other ranger friends that something made the whole world crash around her. It was nearly silent and faster than anything she had ever seen before. It was on them before anyone could move.
 
It was a slaughter. It was almost as if some god somewhere had snapped their fingers and each of the scouts fell. Ripped throats, torn through bodies. Willow tried to stop it, but it moved so swiftly. And then she felt Cecelia’s hand on her arm.
 
She was bleeding and falling and dying. Willow kept trying to heal her, but nothing seemed to work.
 
“Hold on. I love you. I’m trying. Please don’t leave me yet.”
“My love…”
 
Willow always knew she would outlive her beloved. She didn’t think it would happen like this, though.
 
She was the sole survivor of the attack. She explained what she could to the Night King. He was sorry for her loss. He lost his wife all those years ago, but not to something as violent.
 
Sura spent all of her time making sure Willow was eating, bathing, breathing. She kept her friend’s head above water while the grief threatened to drown her.
 
Melrom would occasionally come by to talk and bring food. Louis would usually eat the majority of it, but she would welcome his company. As friends.
 
A year after the attack, the Night King called for Willow. He had a mission for her on the material plane.
